Fast Lock

"Fast Lock" is for those who want to use their touch screen to lock their phone rather than using a physical button.

The app requests permission to "Lock the screen". If permission is granted, screen will be locked by one tap.

Fast Lock has no settings, no ads, no pay!

Permissions:

"Fast Lock" uses the Device Administrator permission.
The only permission required by "Fast Lock" is "Lock the screen" (Under Device Administrator permission).

Uninstall:

In some versions of Android, before uninstalling the app, you may need to deactivate "Lock the screen" permission.
Go to the "Settings - Security - Device administrators" page, uncheck "Fast Lock the Screen" and then select Deactivate on the next step.
Then the app can be uninstalled as usual.
